We look at the division of 507903 by 16 
Our goal is to divide 507903 by 16.

Let's proceed to step 1:
The number 16 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 16

Advancing to step 2:
The number 16 fits into 50 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 48 from 50 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 16

Moving on to step 3:
27 divided by 16 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 16 from 27, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 16

On to step 4:
The number 16 fits into 119 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
If we take 112 away from 119, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 16

Step 5:
When dividing 70 by 16, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3174.0
The remainder is 6 after subtracting 64 from 70.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 16

Advancing to step 6:
When dividing 63 by 16, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 31743.0
If we subtract 48 from 63, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
16 can be fit into 150 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 31743.9
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
When dividing 60 by 16, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 31743.93
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 16 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 31743.937
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31743.9375
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31743.9375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31743.9375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 31743.9375, and the remainder is 0.0.
